Patek Philippe and Their Love For Calendar Complications

MARKING THE DAYS – Explore Patek Philippe’s mastery of the annual and perpetual calendar complications with these two beautiful timepieces


Ref. 5205G-013 Annual Calendar

This model was originally introduced back in 2010 in white gold and two different two-tone dials. A rose gold version with either an opaline white or black lacquered dial followed in 2013. For 2018, Patek Philippe reintroduces the Ref. 5205 with a white gold case and an elegant two-tone sunburst dial featuring a subtle black gradation toward the circumference. Three apertures showing the day, date and month are placed in an arc on the top of the dial, while the bottom half showcases the moon phase indicator. And as the name implies, the watch comes with an Annual Calendar mechanism, which “knows” which months are 30 days long and which ones go up to 31, while only needing adjustments at the end of February.


The white gold case in this watch measures 40mm in diameter and features a rather subtle but skillful innovation: skeletonized lugs.


The watch uses the selfwinding caliber 324 QA LU 24H/206 movement that, once again, comes with Patek Philippe’s patented Annual Calendar mechanism.


The Ref. 5205G-013 Annual Calendar has a shiny black, handstitched alligator leather strap with square scales running along its length.



Ref. 5207P-001 Chronograph

The 2018 incarnation of the Ref. 5207 marks the first time that the model is introduced in platinum. The watch uses the caliber CH 29-535 PS Q movement, which is the very first chronograph with a perpetual calendar, making this a true marvel of mechanical engineering. The intricate workings of the movement can be admired directly through the sapphire-crystal caseback, which, if the wearer desires, the transparent caseback can be interchanged with a solid gold platinum one that comes with the watch. The dial, meanwhile, is designed with excellent legibility in mind and also comes with a tachymeter scale. Finally, a shiny brown, hand-stitched alligator leather strap with square scales complete the Ref. 5207’s presentation.


Often mistakenly referred to as “salmon,” the color of the dial is actually golden opaline.


As is the case with all of Patek Philippe’s watches with platinum cases, the Ref. 5270P-001 features sparkling diamond between the lugs at the 6 o’clock position.


Day of the week and month indicators are placed below the 12 o’clock position. The moon phase indicator above 6 o’clock is flanked by a day/night indicator near 7 o’clock and a leap year indicator by 5 o’clock.
